Perhaps you should try some spelling variations:
presentadas » presentados, presentamos, presentado, presenteadas, presentaadas, presentanadas
presentaban » presentan, presentaron, presentada, presenteaban, presentaaban, presentanaban
presentation » presentacion, presentaron, presentan, presenteation, presentaation, presentanation
present » presente, presenta, presentan
presentea » presenteea, presentaea, presentanea, presente, presenta, presented

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((presentadas OR presentaban) OR presentation) OR present) OR presentea) of the Philippines~".
• Adding a wildcard symbol may retrieve word variants: ((((presentadas OR presentaban) OR presentation) OR present) OR presentea) of the Philippines*.
